Instructor Introduction: Hi, I’m Leslie and this is my second year teaching at SECA. I love teaching physics with all the hands-on stuff we get to do. Before coming to this school, I developed a physics class for White Bear Lake Alternative and I am eager to get to know and help all of you this year!
Course Description: This is a course on the concepts and relationships in physics. Besides learning more about how the universe works, students will practice analytical thinking skills that apply to everyday life. We will do hands-on activities often and sharpen some math skills used to express how things are connected to each other.
Topics Covered:
* Forces
* Electricity
* Motion
* Magnetism
* Work and Power
* Waves
* Momentum and Inertia
* Sound
* Energy and Heat
* Light

Find appropriate time to discuss progress with me
Be realistic about what you can and will get done
Use schoolview on your own to assess your progress
Minnesota Standards:
9P.2.2.1: Forces and inertia determine the motion of objects.
9P.2.2.2: When objects change their motion or interact with other objects in the absence of frictional forces, the total amount of mechanical energy remains constant.
9P.2.3.1: Sound waves are generated from mechanical oscillations of objects and travel through a medium.
9P.2.3.2: Electrons respond to electric fields and voltages by moving through electrical circuits and this motion generates magnetic fields.
9P.2.3.3: Magnetic and electric fields interact to produce electromagnetic waves.
9P.2.3.4: Heat energy is transferred between objects or regions that are at different temperatures by the processes of convection, conduction, and radiation.
MOST IMPORTANTLY: Your fellow students are here working consistently toward the goal of learning physics to get credit. Respect is fundamental to helping everyone achieve that goal.
